DVP64EH00T2 Automate programmable haute performance DELTA DVP-EH3 série

Product Overview

The DVP64EH00T2 (DVP64EH00T2) is a high-end main processing unit from Delta's DVP-EH3 series, representing the pinnacle of the DVP-E line in terms of speed, capacity, and motion control hardware. This "Base Unit" provides a high-density configuration of 64 I/O points (32 inputs and 32 outputs) in a single compact chassis. Engineered for complex industrial machinery such as multi-axis welding robots, high-speed packaging systems, and precise fountain control, the DVP64EH00T2 features a specialized "H Type" architecture optimized for AC power input. Utilizing high-speed transistor outputs, it is purpose-built for applications requiring rapid switching frequencies and sophisticated pulse-train motion control.

Technical Configuration

The hardware architecture of the DVP-EH3 series provides significant upgrades over standard EH2 models, including enhanced execution speeds and expanded register memory. The DVP64EH00T2 features 32 digital inputs and 32 transistor-type outputs (NPN). These transistor outputs are capable of high-speed pulse emission, supporting up to 200 kHz for multi-axis positioning. The unit is equipped with dual communication ports (RS-232 and RS-485) supporting the Modbus protocol for seamless HMI and drive integration. Its large program capacity (up to 30k steps) and high-speed data registers make it capable of handling complex arithmetic and large-scale data logging tasks directly at the machine level.

Technical Specifications

Technical FAQs

How does the EH3 series pulse output capability compare to the older EH2 series?

The DVP64EH00T2 (EH3 series) offers significantly improved high-speed pulse processing. While older EH2 models typically topped out at 100 kHz, the EH3 series supports up to 200 kHz on multiple channels. This higher frequency allows for finer resolution and higher speeds when controlling servo motors with high-density encoders, such as the Delta ASDA-A3 or B3 series.

What is the "H Type" specification for the AC input?

The "H Type" indicates a high-performance power supply design within the PLC that is rated for standard industrial AC voltages (100-240 VAC). It is designed to provide stable internal DC power for the CPU and the local 32 inputs even in environments with minor voltage fluctuations or electrical noise typical of large plant floors.

Can I expand the I/O of the DVP64EH00T2 beyond the 64 built-in points?

Yes. The DVP-EH3 series is highly modular. You can connect right-side expansion modules (digital, analog, temperature, or load cell) to the CPU. The system supports up to 512 I/O points in total, allowing the DVP64EH00T2 to act as the central hub for a very large automation system.

Engineering & Installation Guide

• Transistor Output Load Management: Since the DVP64EH00T2 uses transistor outputs, it is strictly for DC loads (typically 5-30 VDC). For high-speed motion control, ensure the load current does not exceed the rated capacity (typically 0.5 A per point). If you need to switch AC loads or higher currents, you must use interposing relays between the PLC and the field device.

• High-Speed Wiring: When utilizing the 200 kHz pulse outputs for servo control, use shielded twisted-pair cables for the pulse (PU) and direction (DR) signals. Ensure the shield is grounded at the PLC side to prevent electromagnetic interference (EMI) from corrupting the pulse train, which could cause positioning "drift."

• Thermal and Mounting Considerations: Mount the PLC horizontally on a 35 mm DIN rail. To ensure adequate cooling for the high-density 64-point circuitry, maintain at least 50 mm of clearance above and below the unit. Avoid installing the PLC directly above heat-generating components like large VFDs or power transformers.
